Application filed July 8, 1912. Serial No. 707,490.

T 0 all whom it may concern 7 Be it known that I, FRANK F. FARGO, acitizen of the United States, residing in the city of Portland, countyof Multnomah, and State of Oregon, have invented a certain new anduseful Combination Vehicle-Track and Curbstone, of which the followingis a specification.

My invention relates more particularly to an article of manufactureadapted for use as a track or runway for vehicles, especiallyautomobiles, or as a curb stone, and Which may be so constructed as toprovide a conduit for the reception of telephone, telegraph or electricwires and the like.

The invention is preferably made in units, each the counter part ofevery other part, and all adapted to be laid together end to end, withan improved interlocking device to prevent their longitudinal or lateralmovements relative to each other.

In order that others may fully understand my invention, I have shown inthe accompanying sheet of drawings one practical form or embodimentthereof for purposes of illustration, which I will now describe.

In the drawings,- Figure 1 is a perspective view of one and a fractionunits of the invention; Fig. 2 is a fragmentary face view at the end ofone of the units to show the formation to receive the interlockingmeans; and Fig. 3 is a cross sectional view showing my invention set upas a vehicle track, with interlocking and spacing or gage memberstherebetween.

Referring now to the drawings, I will describe one of the units whichare capable of being assembled and connected together for the purpose offorming vehicle tracks, or for the purpose of serving as curb-stones atopposite sides of a street. I prefer to make each unit of an lar form,in cross section, as indicated, an if made of concrete, which material,to reinforce it with bars 11 extendin therethrough. The upper face is ofcurved or concaved form, and is preferably provided with a concavedsheet metal wearing face 2, embedded into the material, as indicated. 1also provide said units with conduits, as 3, which serve, whether saidunits are set up as a curb-stone, or as a track, as an effective andcontinuous conduit for the reception of telephone, te1egraph or electricwires, or any other of the purposes for which such conduits are or mavbe used. Each unit is preferably the coun terpart of every other part orunit and is so constructed that when assembled or set up they fitclosely together end to end. In the form here shown the ends are madesquare and are provided with grooves, as 4, Fig. 2, for the reception ofinterlocking bolts or rods, as 5. In the face and at the back of eachunit, near its ends, are sockets 6 adapted to receive the inturned endsof interlocking plates 7, by means of which, with the bolts or rods 5,said units are locked together end to end and in register with eachother. I prefer that the interlocking plates 7 be also provided with anunderlip, as 7 to rest underneath the meeting ends of said units as afoundation therefor.

In Fig. 3 I have shown how my invention 1s set up to form a vehicletrack, such as is used for running automobiles into garages, although atrack or runway of any length can be made thereof. The units areconnected end to end, as illustrated in Fig. 1, in two lines facing eachother at a space apart, with spacing or gage bars 8 connecting the same,and holding them in proper relationship with each other.

I am aware that changes can be made in the embodiment of the inventionhere shown and described for urposes of illustration and I do not, thereore, limit the invention to the particular form here shown, except as Imay be limited by the hereto appended claims.

I claim:

1. In a vehicle track, in combination, a series of angular shapedmasonry blocks having concaved track surfaces and outside, upwardlyprojecting flange-like portions, and adapted to be connected end to end,interlocking plates having inturned ends and underlips and adapted tofit into and under the meeting ends of said blocks, and connecting boltsadapted to fit between the meeting ends of said blocks and to hold saidplates in interlocking relationship with said blocks, substantially asshown and described.

2. In a vehicle track, in combination, a series of angular shapedmasonry blocks having concaved track surfaces and outside, upwardlyprojecting flange-like portions, and having conduits formedlongitudlnally thereof in their corners, said blocks being adapted to beconnected end to end, with said conduits in alinement with each other,interlocking plates having inturned ends and underlips and adapted tofit into and under the meeting ends of said blocks, and connecting boltsadapted to fit between the meeting ends of said blocks and to saidplates in FRANK F. FARGO.
